AUTOMATIC LIGHT-CONTROLLED FILM-PRINTING APPARATUS.

To all whom it may concern:

.Be it known that 1, DAVID HORSLEY, a citizen of the United States, and a resident of Bayonne, in the cgunty of Hudson and State of New Jersey, have invented certain the printing light. In other printers of this class the control of the light 1s dependent upon the skill and judgment of the operator. The present invention provides an absolutely accurate and automatic control for the light of the printer by the introduction of a resistance coll, portions of which can be introduced or cut out of an electric circuit in series with the light of the apparatus by means of a solenoid. The operations of the latter are controlled by notches made in one of the edges of the negative film used in the apparatus. By means of the appurtenances of the invention more or less intensity of li ht is given by the lam of the apparatus to t e negative, when d negative and undeveloped film pass a light duct which is controlled by a shutter. With the invention the number of patches in a positive film are reatly reduced, as the printing of the di erent scenes on the positive is a continuous operation.

he appurtenances of the invention expose the succeeding portions of the unexposed positive film to varying intensities of light, and produce a uniform positive film from a negative of various photographic densities. The invention permits the assembling of a motion picture negative film infits entirety and by controlling the li ht, permits the development of the positive 1m print in one-roll regardless of the number of scenes or the number of changes in the density of. the negative scenes.

Figure 1 represents a front view of the invention, Fig. 2 shows a right hand side view of Fig. 1; Fig. 3 shows a front elevation of the film propelling device of the invention; Fig. 4 1s a right handside view of Fig. 3; Fig. 5 represents a top view of Fig. 3, Fig. 6 shows a partial section of Fig. 3 on the line 6, 6, Fig. 7 is a partial section of Specification of Letters Patent.

pair of brackets 192 extend from the base so I wire of the coil 220 is fastened to the contact plate 200 and is then wound around the insulated stud 193, between said plate 200 and the next ad acent contact plate 201. The wire of the coil then passes through a slot in the contact plate-201 and is secured in said slot by a plug. The wire then is wound around the insulated stud 193 to form the second coil 221 between the contact plates 201 and 202.

Brushes 265 to 276 extend from'the lower face of the brush bar 260 and are in line and can bear on the contact plates 200 to 211. Spring clamping guides 280 with the lon itudinal openings 281 extend from the %rush bar 260. The said openings 281 are in line with the sprocket wheels 189 when the brush bar 260 is in its closed position. A binding post 282 extends from the side of the base oard 185 and a wire 283 connects the latter bmdmg post with the latch hook 262.

index card 285 with a pluralit of perforat1ons 286 on its face and erfbratlons 287 on 1ts edges is placed on t e front face of theboard 185. The index card is clamped in position on the board 185 by means of the brushes 265 to 277, and the spring clamplng guides 280. The perforations 287 are engaged by the wheels 189 to propel the said index card and the perforations 286 when they come under the brushes 265 to 276 allow the latter to come into contact with the respective contact plates 200 to 211. f

A lamp house is indicated in its entirety by the numeral 295 and comprises the top 296, bottom 297, front frame 298, rear wall 299, and side walls 300. A door 301 is hinged over an opening in one of the side walls 300. A lamp 305 is located in the lamp house 295 and is attached to the top 296. An electric motor 306 is belted to the pulley 126.

A pair of mainline wires are indicated at 314 and315 for a source of electric current and which are connected to switch 316. A w1 re 317 connects the said switch with the b nd ng post 255. A wire 318 connects the b1nd1ng post 256 and the binding post 87 of the switch plate 85'. A wire 319 extends from the switch 316 to the motor 306. A wire 320 connects said electric motor 306 with the binding post 89. A switch is indicated at 322 and has leading thereto a main line wire 323. A wire 324 connects the switch 322 and the binding post 282. A wire 325 connects the binding 0st 236 with the socket of the lamp 305, an a main lme wire 326 extends to said socket.

A film case is indicated in its entirety by the numeral 330. It comprises the side wall 331, door 332, top wall 333, bottom wall 334, front Wall 335, and rear wall 336. It has extending therefrom the legs 337 and 338 by means of which it is secured in lace. A forked leg 340 extends from the eg 338. The forked leg 3.40 has formed therein bearings for a reel 341, and the latter carries a negative film 342. A pair of guide rollers 343, 344 are journaled over an opening in the bottom wall 336. A reel 345 is carried on a pivot 346 in the said case, and carries the ositive film 350. Both the films are then led over the guide roller 159, under the film sprocket wheel 158 and then over the guide roller 168. The film 342 then passes under the presser feet 78 and bears on the front plate 20. The film 350 after passing the roller 168 passes over the feet 78 and then both films pass under the roller and the colored. glass 70. The films are then engaged by the film grip ing pins 120 and are finally discharged rom under the apron 60.

To operate the invention the operator assembles the negative film 342 with the different scenes thereof 'in their proper sequence. The said negative film has been previously notched on one of its sideedges thereby drawn up which causes the ratchet wheels 191 to turn through an angle of one tooth, thereby turning the driving shaft 188 and the sprocket wheels 189. 'This causes the index card 285 to rise the proper distance to separate one of the brushes 265 to 277 from its correspondin conta t l t all of which latter are in icated by thev numerals 200 to 211. This will cause one of the other brushesto make contact with its corresponding contact plate, thereby reducing or increasing the amount of the resistance of the coils 220 to 232, which are in the electric circuit of the lamp 305. The greater the resistance the less intensity of t e light produced by said lamp.

The film printing apparatus is operated by wer being transmitted to the grooved ,u ey 126, and which pulls the negative 342 from the reel 841 and the raw material from the reel 845. The light from the lamp 805 passes through the light duct 145 and through the negative film 342, and thereby prints the positive. Both films are simultaneously moved down durin the period that the solid portion of the utter 152 is assing between the light and the said 1i t duct 145. When a change of scene occurs in the negative. requiring less or more light to give a pro r print from the so enoid which through the intervening 1 mechanism causes the index card 285 to the negative, the. roller 94 rops into one of the notches 352 at the beginning of the next scene, permitting electric contact to be made by leg -91 and contact plug 90. This rmits a flow of electricity through move up in this instance, and brings into contact the proper brush to make the proper contact between it and the contact plate to give the desired intensity of light, by va mg the quantity of resistance in the lig t circuit.
